When the cover is fixed to the base, the cover drivesthe transmission member to abut the moving member. The moving membermoves towards a first direction substantially perpendicular to the baseto connect the at least one conducting part and the circuit board. Asignal is produced by the at least one conducting part and the circuitboard. When the cover is moved out of the base, the moving member movestowards a second direction opposite to the first direction. The at leastone conducting part is moved away from the circuit board and is removedfrom the plurality of receiving holes.

FIGS. 1-2 illustrate one embodiment of an anti-disassembly protectionstructure 100. The anti-disassembly protection structure 100 includes acover 10, a moving member 20 (see in FIG. 6), a transmission member 30(see in FIG. 5), a mounting frame 40, and a base 50.

The moving member 20 includes two conducting parts 22, a connecting part24, an elastic part 26, and a body 28. The connecting part 24 defines aplurality of receiving holes 240 and a fastening hole 242. In at leastone embodiment, the elastic part 26 can be a spring.

The transmission member 30 includes a shaft 32, a first cam 34, a secondcam 36, and two fastening members 38. In at least one embodiment, eachfastening member 38 can be substantially e-shaped. The first cam 34includes a first end 342 and a second end 344. A radius of the first end342 can be less than a radius of the second end 344. A first aligninghole 340 can be defined in the first end 342. The second cam 36 includesa first end 364 and a second end 362. A radius of the first end 364 canbe less than a radius of the second end 362. A second aligning hole 360can be defined in the first end 364. The mounting frame 40 includes apanel 42 and two side plates 44. In at least one embodiment, the twoside plates 44 are extended from opposite sides of the panel 42 and canbe substantially perpendicular to the panel 42. The panel 42 defines athrough hole 420 and a plurality of fastening holes 422. Each side plate44 defines a mounting hole 440. The mounting frame 40 can besubstantially U-shaped.

The base 50 includes two supporting portions 52 and a plurality offastening columns 54. Each supporting portion 52 defines a groove 520.

FIG. 3 illustrates the cover 10 of anti-disassembly protection structure100. The cover 10 includes a circuit board 12 and a driving portion 14.The driving portion 14 is extended from the circuit board 12 and can besubstantially perpendicular to the circuit board 12. The circuit board12 includes a plurality of touch points 120.

FIGS. 4-5 illustrate the housing anti-disassembly protection structure100 being assembled. A plurality of screws (not shown) extend into theplurality of fastening holes 422 and can be engaged with the pluralityof fastening columns 54 to fix the mounting frame 40 to the base 50. Theelastic part 26 is sheathed with the body 28. The body 28 extends intothe through hole 420 and can be engaged in the fastening hole 242. Theelastic part 26 abuts against the panel 42. The two conducting parts 22are received in two of the plurality of receiving holes 240. One of thetwo fastening members 38 is fixed to one end of the shaft 32. The shaft32 extends into the first aligning hole 340, the mounting hole 440 ofone of the two side plates 44, the second aligning hole 360, and themounting hole 440 of another side plate 44. Another fastening member 38is fixed to the shaft 32. The second cam 36 is located between the twosupporting portions 52. The shaft 32 is received in the two grooves 520.

FIGS. 6-7 illustrate an internal structure of the anti-disassemblyprotection structure 100. When the cover 10 is fixed to the base 50, theshaft 32 is rotated by the driving portion 14 via the first end 342 ofthe first cam 34. The second end 362 of the second cam 36 abuts againstthe body 28. The elastic part 26 is deformed by the body 28. The movingmember 20 moves towards a first direction substantially perpendicular tothe base 50. Each conducting part 22 abuts against two of the pluralityof touch points 120. The two of the plurality of touch points 120 areelectrically connected, and produce a signal. If the touch points 120connected to the conducting part 22 are different, the signals producedby the touch points 120 are different. In at least one embodiment, thenumber of the touch points 120 is more than the number of conductingparts 22. The number of conducting parts 22 is different, and thesignals are different.

FIGS. 8-9 illustrate the anti-disassembly protection structure 100 inoperation. When the cover 10 is moved out of the base 50, the drivingportion 14 is moved away from the first end 342 of the first cam 34. Theshaft 32 and the second cam 36 rotate. The elastic part 26 returns to arelaxed state. The moving member 20 moves towards a second directionopposite to the first direction. The connecting part 24 impacts thepanel 42, and the two conducting parts 22 move out of the two receivingholes 240 and move away from the touch points 120. Therefore, it cannotbe known which conducting part 22 connects to which touch point 120.Even if the cover 10 is fixed to the base 50 again, the receiving holes240 receiving the two conducting parts 22 will be different than before.The signal produced by the plurality of touch points 120 will be wrongand a system will stop working to prevent tampering by unauthorizedusers.
